Evan Hancock - Larissa Calwell

Larissa Calwell, played by Leah De Niese, made her first screen appearance on 11 June 2001. De Niese previously appeared in Neighbours as Miranda Starvaggi when she eleven years old. Larissa was described as being a "sly manipulator" by a writer for the 10terrorists press kit. The character became involved in a love triangle between Paul McClain (Jansen Spencer) and Tad Reeves (Jonathon Dutton). Tad pretends to be Paul in a series of emails to Larissa. When they admit what they have been up to, Larissa "turns the tables" on them. Dutton commented "She's hurt when she finds out, but them she turns it to her advantage. She thinks that since she likes both of them, she'll give them both a trial run and then decide who she's most attracted to." Paul and Tad agree to Larissa's plan and try to out do each other on their respective dates. Tim Randall of the Daily Record said "Larissa is loving every minute of having two men fighting for her affections - and she just can't wipe that smug smile off her perky little face."

During a trip to Paris, Paul McClain befriends Larissa. Upon his return to Australia, Paul learns Larissa has been emailing him and Tad Reeves has been replying on his behalf. Paul believes Tad's personality will win Larissa over and he asks him to continue emailing her. Larissa calls Paul and tells him she is coming to visit him. Tad coaches Paul on some of Larissa's interests, particularly dance music. Paul and Larissa's first date goes well and she reveals that she wants to see him again. They go to the Coffee Shop for their next date, where Paul impresses Larissa with his knowledge of music and DJing. Tad tells Paul to make Larissa a mix tape, but when she wants to see him do it, they make an excuse about the mixing equipment being broken. Paul and Tad reveal to Larissa what has been going on and they decide to let her choose between them. Larissa tells them that she will go on a date with both of them and work out who she prefers. The boys initially protest the idea, but Larissa states that they have been messing her around and they relent.

Larissa picks Paul for the first date. They watch a movie and go for a pizza, which results in Larissa and Paul kissing on the doorstep. A few nights later, it is Tad's turn and he takes Larissa on a date which he makes up as it goes along. Larissa realises that while Paul is romantic, Tad is more exciting. Both boys call Larissa again to arrange another date and they confide in Felicity Scully (Holly Valance). Felicity realises what is going on and meets with Larissa to tell her to stop playing games. Larissa states that she is only having a little fun. After her parents catch her chatting online too often, Larissa is taken off the school correspondence course and she begins attending Erinsborough High. Larissa attends Paul's football game and runs into Tad. She tells him she it is a coincidence and that she had just gone for a walk when she spotted the game. Shortly after, Larissa goes to see Tad DJing at a nightclub. Paul also attends the event and catches Larissa and Tad kissing. Larissa leaves, while Paul and Tad fight. However, they realise she is not worth losing their friendship over and they agree to ignore her.
